Hardware
Reviews

In all respects this is the Samsung quality as the original Gear S strap you are currently using, so you know this product well, but it is currently selling for £40 in the UK, which is about $62USD. This is a good product, but it’s at a premium price and you have to ask yourself, Do I really need it?

Turn on your computer from anywhere with an Arduino Server

Filed under
Hardware
OSS

Unless you live off-the-grid and have abundant free electricity, leaving your rig on while you go away on trips is hardly economic. So if you’re like [Josh Forwood] and you happen to use a remote desktop client all the time while on the road, you might be interested in this little hack he threw together. It’s a remote Power-On-PC from anywhere device.

It’s actually incredibly simple. Just one Arduino. He’s piggybacking off of the excellent Teleduino software by [Nathan] who actually gave him a hand manipulating it for his purpose. The Arduino runs as a low-power server which allows [Josh] to access it via a secure website login. From there, he can send a WOL packet to his various computers to wake them up.

From Gongkai to Open Source

Filed under
Hardware
OSS

Compared to the firmware, the hardware reverse engineering task was fairly straightforward. The documents we could scavenge gave us a notion of the ball-out for the chip, and the naming scheme for the pins was sufficiently descriptive that I could apply common sense and experience to guess the correct method for connecting the chip. For areas that were ambiguous, we had some stripped down phones I could buzz out with a multimeter or stare at under a microscope to determine connectivity; and in the worst case I could also probe a live phone with an oscilloscope just to make sure my understanding was correct.

Open hardware is the physical foundation of the open movement. It is through understanding, designing, manufacturing, commercializing, and adopting open hardware, that we built the basis for a healthy and self-reliant community of open. And the year of 2014 had plenty of activities in the open hardware front.

Fedora 21 Released For POWER & AArch64 Hardware

Filed under
Red Hat
Hardware

While Fedora 21 was officially released last week, coming out today is the release of Fedora 21 for the PowerPC and ARM AArch64 architectures.

Fedora 21 and its packages are now officially available for IBM POWER servers as the only PowerPC systems being officially supported by the PPC release. Support for Apple's older PowerPC systems is mentioned as a PPC platform that's most likely broken and will not be working out-of-the-box. Fedora for POWER in the 21 release offers an installer for the Fedora Server product, support for 32-bit Power has been dropped in favor of 64-bit, and there's numerous enhancements to Fedora on POWER compared to older releases.

Generic TrustZone Driver Proposed For Linux Kernel

Filed under
Hardware

ARM's security extensions are in the process of being bettered on Linux.

TrustZone is the marketing name for ARM's security extensions. TrustZone exposes two virtual processors with hardware access controls to let the application core switch between the two virtual states to avoid potentially leaking any information from one state/world to the other. TrustZone has been around going back to the ARMv6 days and there's been Linux support but it's largely been platform specific. Now, however, a generic TrustZone driver might finally come to the Linux kernel.

Qbo Is an AI-Driven Ubuntu-Powered Cute Little Robot - Video

We've seen some interesting devices coming out of the Mobile World Congress in Barcelona and the small Ubuntu-powered Qbo robot is just one them. Linux fans already kind of knew what to expected to see in Barcelona. Many Ubuntu fans were looking to check out the first Meizu MX4 Ubuntu Edition phone and their curiosity was satisfied, but now we have something that it's equally interesting, and that is a small robot.

​No reboot patching comes to Linux 4.0

One reason to love Linux on your servers or in your data-center is that you so seldom needed to reboot it. True, critical patches require a reboot, but you could go months without rebooting. Now, with the latest changes to the Linux kernel you may be able to go years between reboots. Read more

Linux 4.0-rc2

So rc2 missed the usual Sunday afternoon timing, because I spent most of the weekend debugging an issue that happened on an old Mac Mini I have around, and I hate making even early -rc releases with problems on machines that I have direct access to. Even if it only affected old machines that actual developers are unlikely to have or at least use. Today I got the patch from Daniel Vetter to fix it, so instead of doing a Sunday evening rc2, it's a Tuesday morning one. Go get it. It works better for the delay. Other than that little one-liner i915 fix? Not much, actually. It's been a very quiet week, for being this early in the release process. Sure, 3.19-rc2 was even smaller, so it continues a trend, but that was the xmas week. I hope this low volume is just because the 4.0 merge window itself was somewhat calmer than most recent releases. But I suspect the real reason is that the driver and networking trees from GregKH and davem are pending, and didn't make rc2. We'll see. Anyway, the shortlog is appended, and testing is appreciated, Linus Read more
